NICI Management CDR Presentation
AO Procurement • Status of MOU • Has been reviewed and agreed upon • IFA director has agreed to support the project • MOU is going through approval and signature process
AO Procurement Schedule Delivery of APDs(MKIR Purchased) to IFA As soon as received(Sept 02) Lab testing of all components using UH lab optics Nov. 2002 to June 2003 Delivery of NICI Optical bench and optics to IFA May 2003 Testing of components in NICI bench – May 2003 May 2003 to June 2003 Delivery of tested working system to MKIR(Hilo) End of August 2003
AO Procurement Avalanche Photodiodes (APD) Apds have been ordered Expected delivery is much improved at Sept. 2002 Price is as expected

AO Procurement IFA Payment Milestone Schedule 20 % at completion of Start of Work 20% upon completion of the DM construction 30 % upon successful lab tests 30 % upon completion and acceptance
Optics Procurement • Optical Fab drawings are complete • Key Vendors have been selected • SSG Inc for OAPs • ISP for spheres and flats • Requirements trades-offs made • Orders will be ready to place after CDR
Tracking and Controlling Changes to Drawings • Changes are made only two ways • Revision to original print by Mechanical Engineer that is reissued to machine shop via electronic PDF file • Marked up print at machine shop or assembly lab indicating small change made • Marked up drawings are then sent to ME in batches to update the model
Tracking Fabrication of Parts • Parts are sent for fabrication in work packages that correspond to parts need for each integration step. Often a few work packages will make up the parts needed for each integration step. • There is a master list of parts for each step • As parts are received they are cleaned, bagged, labeled and checked off on the master list
Tracking Fabrication of Parts • For items with long construction times progress will be monitored by asking for periodic updates from the vendor. This would typically be done 1time/month for major items such as optics and machine shop parts. • Some items such as the vacuum jacket or optics will require in-person visits it ensure that quality and schedule goals will be met
Parts Testing • Keys to getting accurate parts • Careful vendor selection • Detailed vendor documentation • Inspection when possible • Subassembly parts inspected at first “dirty” assembly shortly after received • Optics accuracy relies on vendor documentation
Parts Storage • Machine shop parts are cleaned, bagged and labeled by part number and stored in cabinets by subassembly • Purchased parts will stored with the machine shop parts by subassembly • Off the shelf equipment items will have a NICI sticker attached and given an inventory number
Subsystem Assembly and Testing • Structures • Alignment measured as assembled • Mechanisms • Tested “dirty” and fitted • After fitting they are painted and polished • Cold testing upon integration • Optical checks to verify proper function
Integration Phase Resources • Electronics will be built, integrated and tested at the MKIR office in Honolulu and shipped to Hilo once complete. • Peter Onaka • Jim Hinds • Technician
Integration Phase Resources • Mechanical and optical structures will be integrated and tested at the MKIR office in Hilo • Doug Toomey • Dayton Jackson Machine Works • Technician • MKIR Engineer • Jim Hinds
Cash Flow • The NICI payment plans as designed to provide a starting surplus of $200K that would build to $500K after the CDR. The Surplus would remain at $500K until the integration phase. • In reality this amount varies over the three month payment interval
Safety ReviewDetailed documentation in SDN1013 NICI Safety Issues NICI Safety Policy Safety has utmost priority in the design and operation of NICI. All staff involved in the NICI design and construction must place the highest priority on the safety of those that will use NICI. If at any time there is the possibility of risk to safety it should be brought immediately to the attention of the Project Manager. NICI must comply with all relevant notified Site Safety Requirements applicable to Mauna Kea and Cerro Pachon and conform to good, safe engineering practices
